This method works for the MFC derived class and was tested on a Dialog-based class.

1. Set Active Project
2. Select Project –>Add to Project –>Components and Controls –> VC++ Components –> ToolTip Support
3. Insert!
4. CDialog::OnInitDialog() refer the following:

    	// TODO: Use one of the following forms to add controls:	// m_tooltip.AddTool(GetDlgItem(IDC_), );	// m_tooltip.AddTool(GetDlgItem(IDC_), "");	m_tooltip.AddTool(GetDlgItem(IDC_Smile), "Click here to see smile");

Explanation:


1. .h file: Add the following inside the Constructor:
   

    	public:	   virtual BOOL PreTranslateMessage(MSG* pMsg);	protected:	   CToolTipCtrl m_tooltip;	   Virtual BOOL OnInitDialog();

2. .cpp file: Add 2 methods:
   

    		PreTranslateMessage(MSG* pMsg);	   ***will add CToolTipCtrl::RelayEvent()	OnInitDialog();
